Condyloma Acuminatum: Clinical Overview and Management

Pathophysiology and Epidemiology

The Centers for Disease Control and Prevention (CDC) states that condyloma acuminatum (genital warts) is caused by human papillomavirus (HPV) infection, predominantly low-risk types 6 and 11, which account for approximately 90% of cases 1, 2, 3
The American Academy of Otolaryngology-Head and Neck Surgery notes that HPV types 6 and 11 are sexually transmitted and cause benign fibro-epithelial proliferative lesions of genital epithelium 4, 5
High-risk HPV types 16 and 18 may also be present in genital warts and are strongly associated with dysplasia and squamous cell carcinoma 4, 5, 3

The CDC recommends that diagnosis of genital warts should be made by visual inspection alone in typical cases 1, 2
The American Academy of Otolaryngology-Head and Neck Surgery states that biopsy is indicated when diagnosis is uncertain, lesions fail standard therapy, disease worsens during treatment, patient is immunocompromised, or warts are pigmented, indurated, fixed, bleeding, or ulcerated 5, 6
The CDC notes that acetic acid application (acetowhitening test) is NOT recommended for routine screening as it has high false-positive rates and lacks adequate specificity and sensitivity 6

The CDC recommends that first-line treatment options for external genital warts include patient-applied topical agents or provider-administered destructive therapies 1, 2
The CDC states that cryotherapy with liquid nitrogen is a recommended treatment option for genital warts 1, 2, 7
The American Academy of Otolaryngology-Head and Neck Surgery notes that surgical removal/excision is recommended for oral lesions and can be used for genital lesions 4, 7

The CDC recommends that patients must understand that genital warts are not life-threatening and rarely progress to cancer, but HPV is a sexually transmitted infection that can be transmitted even when warts are not visible 1, 2, 7
The CDC states that the quadrivalent HPV vaccine (Gardasil) protects against HPV types 6 and 11 (causing 90% of genital warts) and types 16 and 18 (causing 70% of cervical cancers) 1, 2, 7
The CDC recommends that vaccine is most effective when administered before sexual contact 1, 2, 7

The American Academy of Otolaryngology-Head and Neck Surgery notes that key differentials to distinguish from condyloma acuminatum include other HPV-related lesions and non-HPV papillomatous growths 4, 3
The CDC states that verruca vulgaris (common wart) is caused by HPV types 2 and 4, presents as well-circumscribed flesh-colored growths with white pebbly surface, and occurs via autoinoculation from fingers to mouth 4, 3, 8
